The Supreme Court just ruled a law as unconstitutional that prevented corporations (which are legal "persons") from making political contributions.
And the Democrats are howling. They say that it is "un-American" for companies to make political contributions. Companies for whom their interests lie in smaller, less-restrictive government and lower taxes.
But those same Democrats say that is is perfectly fine for labor unions to make political contributions. Unions whose interests lie in more regulation and larger government, even at the expense of the companies who pay the bills.
